Why should the pre-treatment step of air scrubbers include moisture removal

In the field of environmental protection, air scrubbers play an indispensable role as an efficient air pollution control equipment. Its main function is to remove particulate matter and harmful gases contained in industrial emissions through physical and chemical reactions to ensure that air quality meets national emission standards. However, the efficient operation of an air scrubber relies on the precise execution of its pretreatment steps, especially the critical step of moisture removal.

The importance of moisture removal in air scrubber operation cannot be ignored. First, the removal of moisture helps prevent equipment clogging and corrosion. If the moisture in the flue gas enters the air scrubber without treatment, it may react chemically with the internal components of the equipment, causing blockage or corrosion of the equipment. Especially when acidic gases are present in the flue gas, moisture will accelerate the corrosion process and significantly shorten the service life of the equipment. Therefore, removing moisture from flue gas is not only a necessary measure to protect the internal components of the air scrubber, but also the key to ensuring long-term stable operation of the equipment.

Secondly, moisture removal can significantly improve the treatment efficiency of air scrubbers. When the moisture content in the flue gas is too high, it will occupy the reaction space inside the scrubber, resulting in a reduction in treatment efficiency. In addition, moisture may react with certain pollutants in the flue gas to form compounds that are difficult to treat, further adding to the complexity of treatment. Therefore, removing moisture from the flue gas will help improve the purification effect of the scrubber and ensure that the flue gas emissions comply with national standards.

In addition, moisture removal can effectively reduce wastewater discharge. When treating flue gases containing large amounts of moisture, air scrubbers produce large amounts of wastewater. If these wastewaters are discharged directly without proper treatment, they may cause secondary pollution to the environment. Therefore, removing moisture from flue gas not only reduces the amount of wastewater produced, but also reduces the negative impact on the environment.

Finally, moisture removal also helps reduce air scrubber energy consumption. When the moisture content in the flue gas is too high, the equipment needs to consume more energy to heat the flue gas or perform other treatments to remove the moisture. By effectively removing moisture, energy consumption can be reduced, the economic efficiency of the equipment can be improved, and the sustainability of the overall operation can be improved.
